WWDC26, 48 hours later: what actually shipped.
The 48-hour receipt: v0.4.30 hit npm and PyPI on June 9 with App Intents schema macros, Spotlight indexed entities, Foundation Models scaffolds, and a nightly Apple API watcher — plus what the keynote changed for agent-authored Apple software.
Before the keynote we said we'd ship support for whatever landed, within 48 hours. Here's the receipt.
v0.4.30 — on npm and PyPI June 9
The keynote was June 8. v0.4.30 shipped the next day with the first wave of WWDC26 surface support:
- **App Intents schema macros.**
defineIntentdefinitions can now declare Apple's new assistant schemas, and the generated Swift carries the schema conformances Siri's orchestrator expects. - **Spotlight indexed entities.** Generated entities pick up the semantic-index metadata that puts third-party content inside Siri AI's personal-context surface.
- **Foundation Models, Private Cloud Compute, and Image Playground scaffolds.** Templates that compile against the new FM session surface, including the PCC-backed model path with no API keys.
- **A nightly Apple API watcher.** A scheduled job diffs Apple's published interfaces every night, so SDK drift shows up as a failing check instead of a user bug report.
What the keynote changed for this project
Apple made coding agents first-class in Xcode — MCP tools and the Agent Client Protocol are now plugin types, not hacks. That is the thesis this compiler was built on: agents author Apple-native features, and the hard part is making the output hold up under Apple's platform rules.
App Intents got promoted again, too. Siri AI's orchestrator runs on the Spotlight index and the App Toolbox, and schema-conformant intents are the path in. If your intents are generated and validated, you ride that wave without rewriting anything.
Next
The next release is already on deck: two new validator diagnostics pulled from real-world Swift failures, a dogfood routing mode for the suggest tool, and three new templates — a custom LanguageModel provider session, a DynamicProfile session, and an AppIntentsTesting harness emitter that generates the XCTest file alongside the intent. The harness work matters: Apple shipped a first-party way to test intents this year, and generated intents should arrive with their tests.
Numbers, as always, are on the [proof page](/proof) and regenerated from the compiler on every release. If something here doesn't match the repo, file an issue.
